The Hammers 3-9x40AO rifle scope aims to provide airgun enthusiasts, particularly those wielding .177 and .22 Magnum spring-powered rifles, with a versatile and reliable optic. This review will delve into the technical specifications, design elements, optical performance, build quality, mounting system, and overall user experience of this scope, offering a comprehensive analysis for potential buyers.
Core Specifications and Design Philosophy
At its heart, the Hammers 3-9x40AO is a variable power rifle scope, offering a magnification range from 3x to 9x. This versatility allows shooters to engage targets at varying distances, utilizing lower power for wider fields of view and closer shots, and higher power for enhanced detail and precision at longer ranges. The 40mm objective lens diameter strikes a balance between light-gathering capability and overall scope size. A larger objective lens generally allows more light to enter the scope, potentially resulting in a brighter and clearer image, especially in lower light conditions. However, an excessively large objective can lead to a bulkier and heavier scope.
The inclusion of an Adjustable Objective (AO) is a significant feature. Parallax, the apparent movement of the reticle in relation to the target when the shooter’s eye position changes slightly, can introduce significant aiming errors, especially at closer ranges and higher magnifications. The AO mechanism allows the user to rotate the objective lens housing to focus the image of the target and the reticle onto the same focal plane, effectively eliminating parallax at a specific chosen distance. The advertised close focus capability of 5 yards at lower magnifications suggests a design consideration for airgunners who often engage targets at relatively short distances.
The scope body is constructed from aluminum, a common material in rifle scope manufacturing known for its lightweight yet durable properties. This helps to keep the overall weight of the scope manageable (24 ounces) without compromising structural integrity. The black finish is standard for tactical and hunting optics, offering a non-reflective surface.
The Hammers scope is explicitly designed for .177 and .22 Magnum spring air guns. This is a crucial point, as spring-powered air rifles generate a unique double recoil impulse that can be detrimental to scopes not specifically built to withstand it. This designation implies that the internal components and construction of the Hammers scope are engineered to handle these stresses, potentially offering greater longevity compared to scopes designed for firearms with different recoil characteristics.
The package includes a mount, which is a significant convenience for buyers as it eliminates the need for a separate purchase and ensures compatibility between the scope and the provided mounting hardware. The specific type of mount (e.g., dovetail, Picatinny) is not explicitly stated in the provided information, which is a detail potential buyers would need to confirm.

Optical Performance: A Critical Examination
The primary function of any rifle scope is to provide a clear and accurate sight picture. Evaluating the optical performance of the Hammers 3-9x40AO involves considering several key aspects:
Image Clarity and Sharpness:
The user experience is heavily influenced by the clarity and sharpness of the image produced by the scope. A good scope will offer a crisp and well-defined view of the target across the entire field of view and throughout the magnification range. Factors such as the quality of the glass elements, lens coatings, and internal baffling contribute to image clarity. Multi-coated lenses are crucial for reducing reflections, increasing light transmission, and enhancing contrast. The level and type of lens coatings used in the Hammers scope are not specified in the provided information, which is a potential area for further investigation.
Light Transmission and Low-Light Performance:
The 40mm objective lens plays a role in the scope’s ability to gather light. While not the largest available, it should provide adequate brightness for most daytime shooting conditions. However, the true low-light performance depends heavily on the quality of the glass and the effectiveness of the lens coatings. A scope with excellent light transmission will maintain a bright and usable image even in dawn or dusk conditions. User reviews often provide valuable insights into the real-world low-light capabilities of a scope.
Field of View (FOV)
The field of view refers to the width of the area visible through the scope at a given distance. It is typically expressed in feet at 100 yards. While the exact FOV specifications for the Hammers scope at different magnifications are not provided, a variable power scope will have a wider FOV at lower magnifications and a narrower FOV at higher magnifications. A wider FOV can be advantageous for locating targets quickly and tracking moving targets, while a narrower FOV at higher power allows for more precise aiming.
Parallax Adjustment
The adjustable objective is a key feature for airgun shooting, where engagements often occur at closer ranges than with firearms. The ability to dial out parallax ensures that the reticle remains fixed on the target regardless of minor shifts in the shooter’s eye position. The advertised close focus of 5 yards suggests a well-designed AO system catering to the specific needs of airgunners. The smoothness and precision of the AO ring are important for making accurate adjustments.
Eye Relief
Eye relief is the distance between the shooter’s eye and the ocular lens when a full field of view is visible. Adequate eye relief is crucial for comfortable shooting and for preventing recoil-induced scope bite, although this is less of a concern with air rifles compared to high-powered firearms. Consistent eye relief across the magnification range is also desirable.
Reticle Design
The type of reticle used in the Hammers scope is not specified in the provided information. Common reticle types for hunting and general shooting include duplex reticles (with thick outer posts tapering to a fine crosshair in the center) and more complex reticles like mil-dot or MOA-based designs, which can aid in holdover and range estimation. The fineness and clarity of the reticle are important for precise aiming without obscuring the target, especially at higher magnifications.
Build Quality and Durability: Handling the Airgun Recoil
Spring-powered air rifles are known for their unique and often violent recoil, which can be detrimental to scopes not designed to withstand it.
